Woman gives birth at 66

A 66-year-old woman gave birth to a baby girl. She had been receiving fertility treatment for almost ten years before being artificially inseminated. I am concerned with this news because I think that She is too old to have a baby. By the time the baby turns to 20, The woman will be over 85 years old. What if the woman passes away before the baby grow up. Well, I understand how the woman feel but I just think She was being selfish. She had other choices such as adapting a baby without going trough high risks.
